LOOSE-LEAF BINDER'.

Application filed September l., 1,925. Serial No. 54,395.

My invention relates to binders for loose leaf lilino', and particularly to binders adapted to clamp, by adjustable and movable means, the leaves which are tiled, and also provide for adding' to, or taking from, the quantity tiled.

The object of my invention is to provide a simple, durable and practically inexpensive, binder which may be easily and quickly operated for releasing pressure upon leaves filed, so t-hat ready access .may be had to the same, and such leaves as desired removed therefrom, or any quantity, up to the capacity of the file, be added thereto.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Fig. 1 shows a side elevation view, partially in section, of my improved binder;

Fig. 2 shows a perspective view of a part of my binder, the dotted line indicating the movable position of the upper cover and clamping means when the securing rod has been removed;

Fig. 3 and Fig. t indicates the manner in which the body portion of my clamping means is secured to the back of the file;

Fig. 5 is a front elevation view of the body portion of the clamping means after it is secured to the back.

Referring to the accompanying drawings the reference numeral is used to indicate the bottom cover of my file, the numeral 11 the top cover, and the numeral 12 the back, the back and covers being joined in the usual flexible manner by, preferably, cloth strips pasted to, and joining, the back and covers. Extending' upwardly from thc bottom cover are a plurality of securing` posts 13 designed to function for receiving perforated sheets 111. lThe numeral 15 indicates a lock plate, preferably formed of metal, perforated to tit over the posts 13 and also having its inner end extending beyond the tiled sheets and towards the back, there being a perforation, preferably contrally located, in this extending portion and beyond the line of the tiled sheets, to receive the securing rod, or pin, 16.

To the back 12 I have secured th body portion of my securingmeans which consists of a plate 17, provided centrally and longitudinally with a forwardly projecting portion 18, this portion being slotted trans* "width to rc 'eive the plate l5.

versely, as at it), the slots being of sniiicient The projecting portion 18 projects forward sufficiently to form between the plate and the baci; 12

channel to receive the pin 1G.

rllhe body portion 1T of my locking means is provided with hook extensions 2t) adapted to curve over the baci: and clamp into the rear surface of the back, thereby securely and rigidly securing the body portion 17 to the baci; 12. rlhis construction is shown in Figures 3 and l, the lower hook in Fig. 1- being clamped into the back, and the upper hook being in its normal position as it comes from the die and ready to be bent down and clamped into the back.

lt is obvious that the part 18 of the body portion and the central orifice in the plate 15 are so arranged that in assembled position with the plate 15 extending into one of the slots in a protruding portion 18, the cent al ori tice in the plate 15 will lie within the channel formed between the projecting portion 18 and the back 12.

ln the practical operation the sheets 111, to be tiled, are threaded on the posts 13. The plate 15 is then also threaded on the posts 13 and forced downwardly until it compresses the sheets 14.. At this time the back 12 is lying away from the sheets and it is now brought forward and the body portion 17, carried by the back, is moved forward, the plate 15 entering one of the slots 19. The securing rod, or piu, 16, is then threaded downwardly through the channel formed between the projecting portion 1S and the back 12, and through the orifice in the plate 15 which extends into this channel. lt is obvious this iirmly locks the back to the plate 15, and the plate 15 is rigidly held in its position by means of the posts 13, and the plate 15 entering into one of the slots 19 and the rod 1G locking it ln my drawings I have illustrated a preferred form of construction for my invention but I do not wish to be understood as limiting my protection to the specific structure as shown and described, for my invention contemplates other forms of construction, as will be obvious.

Having thus described my invention, what l claim and desire to secure by Letters Pat,- ent ot' the United States is:

1. A. loose leaf binder comprising abottom cover, a top cover and a back, joined by flexible means; e plate, provided With :1 eentirally protruding portion, secured to the beek` and trainsverse slots in said plate; liling posts secured to the lower Cover; :t lock plete, orilieed to lit over the tiling posts, eenstrueted so as to protrude toward the beek and beyond the sheets to be tiled, :1nd being ot such thickness es to he adapted to ent er the slots in the aforesaid plete, there beii'rg an oritiee in said locking plate .so arranged es to lie. Within the Slotted portion ot the beek plate; zi securing pin adapted to lie within the protruding portion of the heel; plate and to pese through the oril'lee in the locking plate7 substantia\ll \Y es shown and described.

2, A loose leef binder comprising an npper and lower cover and :i back, llexibly joined together; a beel plete, haring n eentrzil raised portion provided with trsnsrerse slots therein, secured to the beek; tiling' posts en the lower e rer; e loekingplnte orilieed to ride on said posts, the inner end or plate being orilieed, seid inner end be L adapted to seleetivel)T lie within one ol the slots in the back plate; t securingl pin adepted to be threaded into the protruding portion of the beek plate and to pees through 3. A loose leaf binder eon'rprising :i lower cover, an upper Cover and a hach, flexiblyr joined together; :tiling posts on the lower cover; zz locking plate orilieed to ride on said tiling posts and extend inwardly beyond the sheets to he filed, there being en oriliee oentrelly neer the inner edge thereof; e. receptacle secured to the back; ineens whereby the forward end o1" the locking' pleite extends into the receptacle eeenred to the beek of the roluine5 and ineens to leek the plete iu said receptacle.
